All those 5 changes have been made in DesireData tonight. I justify this
by the fact that no externals in the pd cvs are using gpointers
explicitly; so, compatibility is preserved. All gpointers will use a pure
refcount system, without weakrefs. Note that this is all "in theory",
because gpointers are currently unsupported in DesireData, but I'm
confident that I made all the big changes that needed to be done and the
rest of the work will be easy when gpointers are rehabilitated.

This can't be done as long as the current atom system is supported (the
new atom system will have stuff like atom_init, atom_delete, etc),
because, unlike the string-vs-symbol case, i don't have much of a fallback
if new-style A_POINTER is not supported. Anyway before doing that change I
also have to remove g_next, so, this may take a while...
